Site Planning & Design Flashcards
a sievelike device at the entrance to a storm sewer which traps matter that could block the sewer
catch basin
a street, alley, or other thoroughfare or easement permanently established for passage of persons or vehicles
way
a semicircular open area, with or without a roof, providing a continuous seat
exedra
the number of degrees north or south of the equator of a point on the earth’s surface
latitude
the soil layer beneath the topsoil
subsoil
the level below which the subsoil is completely saturated with water. Also called the ‘water table’
groundwater level
the study of the total pattern of relations between a community or organisms and its environment
ecology
the process of controlling, collecting, transporting, and disposing of excess water
drainage
a partial obstruction against flow, in a duct or pipe
baffle
land on which buildings have not yet been constructed, but which contains utilities and streets
improved land
the ratio of the area covered by buildings to the total lot area, expressed as a percentage
land coverage
the land surrounding a flowing stream over which water spreads when a flood occurs
flood plain
a type of residential siting in which a series of housing units are grouped closely together and surrounded by open space
cluster
a horizontal plane elevation used as a reference for other elevations in surveying and mapping
datum
a road or path reserved for bicycle traffic
bikeway
the temperature of air at which the water contained in the air begins to condense and form dew. It is therefore the temperature at which the air is at 100% relative humidity
dew point
the amount by which the average outdoor temperature at a particular location is below 65 degrees Fahrenheit for one day. degree days may also be summed and stated for a month or year
degree day (dd)
the intersection of two roads at different levels so that vehicles may move from one road to the other without crossing the stream of traffic. Also called ‘interchange’
grade separation
the extension of a building into the property of another
encroachment
inclination or slant, especially of the ground surface
slope
paving using crushed stone
macadam
a horizontal angle measured clockwise from north or south
azimuth
a bank of earth, often piled up against a wall
berm
concrete used for paving which uses crushed granite as the coarse aggregate
granolith
a graded flow path used in open drainage systems
swale
the prevailing or average weather conditions of a place as determined over a number of years
climate
the boundary line of a lot
lot line
the angle which the sun makes with the horizon
altitude
The smallest identifiable parcel of land in a city
lot
the net ground area of a lot which can be covered by a building after required setbacks and other zoning limitations have been accounted for
buildable area
a landscaped strip of ground between a pedestrian walk and a street
planting strip
having no environmental barriers, thereby permitting free access and circulation by the handicapped
barrier-free
Reflectivity measured as the relative permeability of a surface to radiant energy flowing in either direction
albedo
a division of urban land, normally private property, which is surrounded by public streets, and which is officially established and recorded
block
an imaginary line on the ground surface connecting all points of equal elevation
contour
removing and/or adding earth in order to bring the ground surface to a specified elevation or profile. Also called ‘earthwork’
grading
a pattern of land use which develops along a line, such as a highway or river
linear pattern
the elevation of a specified point on the ground or on a structure
spot elevation
designing the external physical environment in which buildings and structures are placed
site planning
flow from a culvert, sewer, or other channel
discharge
any public way or thoroughfare 10to 16 feet in width which has been dedicated or deeded to the public for public use
alley
the level below which the subsoil is completely saturated with water. Also called the ‘groundwater level’
water table
a very large area of land in which all through traffic is eliminated, but which may be penetrated by culs-de-sac or minor loop roads
superblock
space provided for vehicular parking separate from the dedicated street right-of-way
off-street parking
a plan of a city or subdivision, showing the boundaries of individual properties
plat
a space, open and unobstructed to the sky, located at or above grade, and bounded on three or more sides by the walls of a building
court
one or more spaces designated for physically handicapped persons, requiring special design and dimensions
handicapped parking
an underground pipe or drain used to carry off waste matter
sanitary sewer
an open, unoccupied space, other than a court, unobstructed to the sky, on the lot on which a building is situated
yard
the process of determining location, form, and boundaries of a parcel of land by measurement, computation, and drawing
survey
Removing and/or adding earth in order to bring the ground surface to a specified elevation or profile. Also called ‘grading’
earthwork
The rate of slope between two points on a surface, determined by dividing their vertical difference in elevation by their horizontal distance apart
gradient
a legal boundary of a parcel of land
property line
a sewer for carrying away surface rain water, an opposed to sanitary sewer
storm sewer
